Features The thickness gauge is used to measure the thickness of plated and coated sheets on metal, such as paint, enamel, or chrome on steel, and paint or anodizing coatings on aluminum or copper. The gauge features a precise integrated probe and operates on the principles of electromagnetic induction and eddy current effect, automatically detecting substrate attributes. It is essential for material surface treatment and designed for non-destructive measurement of coating and paint thickness. Widely used in manufacturing, metal processing, chemical industries, and commodity inspection, it performs reliably in laboratories, workshops, and outdoor environments. This portable thickness tester includes a high-resolution display and is suitable for inspecting used vehicles to identify repainted surfaces.
